چکیده

In this paper we present the initial design, implementation and result of a small-scale prototype of Visible Light Communication using simple LED and a photodiode. Data is transmitted through visible light by sending data in a binary format as on and off that varies in frequency faster than the human eye can follow. The data to be transmitted is encoded and sent. The data is decoded back at the receiver. Visible Light Communication is the latest technology for communication as it eliminates the use of a radio channel and it is much more secure. This implementation aims to attain an efficient and reliable communication link with considering sufficient improvement with the factors of trade-off such as the distance between the transmitter and receiver for communication and to attain the fastest possible data rate.

Image Sensor Based Visible Light Communication and Its Application to Pose, Position, and Range Estimations

This study introduces an image sensor based visible light communication (VLC) and its application to pose, position, and range estimations. There are two types of visible-light receiver: a photodiode and an image sensor. A photodiode is usually used as a reception device of VLC, and an image sensor consisting of a large number of pixels can also be used as a VLC reception device. A photodiode d...

Demonstration of bi-directional LED visible light communication using TDD traffic with mitigation of reflection interference.

In this work, we experimentally demonstrate a bi-directional transmission link using light emitting diode (LED) visible light communication (VLC) for both downlink and uplink paths. Time-division-duplex (TDD) is proposed and demonstrated to significantly eliminate the reflection interference in VLC. A free space bi-directional transmission of 2 m using simple on-off keying (OOK) modulation with...
